There is disclosed a heat pump comprising a vapor-compression refrigeration system wherein the heat pump evaporator extracts heat from a low temperature heat exchanger in the form of a water-immiscible fluid, and delivers the extracted heat to another location by means of a condenser. The water-immiscible fluid is maintained at a temperature of virtually 0 DEG C. by the injection of many small droplets of water that freeze to form beads of ice as they settle in the fluid. The beads can then be separated and delivered to a combined ice-water reservoir. The heat extracted from the water-immiscible fluid and the injected water droplets is replaced in the ice-water reservoir from natural heat sources, such as a ground loop, a solar panel or an air-water heat exchanger. The heat provided by the ice-water reservoir includes its latent heat of fusion, which acts as a buffer when heat demand exceeds the rate of heat available from natural sources.
